Question

我分区中的节点一直在“健康状态” =“正常”和“健康状态==未知”之间切换。有时节点会消失。

我尝试删除服务，应用程序并取消设置类型，然后重新部署，但是我遇到了同样的问题。

这是一个Service Fabric状态服务，并且在本地运行良好，我遇到的问题仅在我的开发环境中。

我正在使用5个节点。

Answer 1

不确定此问题的哪一部分已解决。但这是我所做的，并且现在可以正常工作：

在ServiceManifest.xml中，我添加了HasPersistedState = true：

<StatefulServiceType ServiceTypeName="Integration.Optical.ServiceType" HasPersistedState="true" />

我移动了应用配置代码

ServiceRuntime.RegisterServiceAsync...

从Service.RunAsync()到Program.Main()

Service Fabric资源管理器运行状况未知
